IMPORTANT SAFETY INSTRUCTIONS

EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong

grounding-type plugs and 3-pole cord connectors

that accept the plug from the product. Use only

extension cords that are intended for outdoor use.

These extension cords are identified by a marking

"Acceptable for use with outdoor appliances; store

indoors while not in use." Use only extension

cords having an electrical rating not less than the

rating of the product. Do not use damaged

extension cords. Examine extension cord before

using and replace if damaged. Do not abuse

extension cord and do not yank on any cord to

disconnect. Keep cord away from heat and sharp

edges. Always disconnect the extension cord from

the receptacle before disconnecting the product

from the extension cord.

WARNING – To reduce the risk of electrocution,

keep all connections dry and off the ground. Do

not touch plug with wet hands.

AVOID CAVITATION DAMAGE

Cavitation is the formation and collapse of

gaseous cavities in a liquid causing severe wear

or eroding of the metal surfaces in the pump. The

most common cause of cavitation is when the

pump is starved for water or if leaks are allowing

air to get into the pressure washer pump. The

most obvious sign of cavitation is a hammering

noise. This noise can be either constant or

intermittent depending upon the degree of

cavitation and damage to the pump. Persistent

cavitation will eventually cause flow and pressure

to decrease. It is important to carefully check your

system during assembly and operation to avoid

the serious damage that can be caused by

cavitation. Check your system for these

conditions which may contribute to, or directly

cause, cavitation:

1 Inadequate inlet line size

2. Insufficient inlet flow or excessive suction

3. Excessive inlet line length

4. Rigid inlet plumbing

5. Too many elbows and/or fittings

6. Excessively hot inlet water

7. Air leak in inlet plumbing

8. Agitation in supply reservoir

9. Clogged inlet filters
